Reference View is a new view mode available in the Develop Module that allows you to compare 2 different images in order to make them visually consistent. This is helpful when making a group of images from a single event look similar or setting the white balance appropriately in mixed lighting conditions.

To get started,

Go to the Develop Module

Click on Reference View. Its on the Toolbar, and you may need to show the Toolbar if hidden

Drag and Drop your Reference Photo onto the left pane. You can change your Reference Photo by either dragging a different image onto the left pane or using the “Set as Reference Photo” context menu in the Library Module.

Edit the active photo. Use the Reference Photo to guide your editing decisions.

The-Digital-Picture has completed their review of the Sigma 12-24mm f/4L DG HSM Art.

Image Quality

From the always-important image sharpness perspective, this lens is a very good performer with a caveat that I will of course explain. At f/4, this lens is quite sharp in the center of the frame over the full focal length range aside from performance becoming modestly softer from 20mm through 24mm. Stopping down to f/5.6 brings sharp center of the frame results to the entire focal length range……….

……… I mentioned the caveat. What I didn’t notice during this shoot was focus shift. As this lens is stopped down, the plane of sharp focus shifts farther away. Because Canon cameras focus with a wide open aperture, this change is not accounted for during either viewfinder or Live View-based focusing (AF or MF). Stopped down manual focusing in Live View will account for the change, but … this is not how we typically focus. Read the full review

It looks like Sigma has another winner on their hands with the 12-24mm f/4 DG HSM Art series lens, especially when you factor in the fact it costs about $1000 less than the Canon EF 11-24mm f/4L.
